An optical detection apparatus includes an optical/electric converter to transduce light incident on the optical/electric converter into a current flowing to a ground potential; a current mirror to supply a mirror output voltage to a current mirror output node in response to an enable signal, the mirror output voltage having a magnitude proportional to the light intensity incident on the optical/electric converter; and a switch to connect a driving node of the current mirror to the ground potential through the optical/electric converter in response to the enable signal.
